U-value calculations
U = 1 / (Rinside + Routside + Rint-clad + Rins-1 + Rmembrane + Rins-2 + Rwind-ins-3 + Rfacade)
In W/m²K
R = d/k in
d = thickness in m
k = conductivity in W/mK
R = Resistance in m²K/W
Rinside = 1/25 = 0.04
Routside = 1/8 = 0.125
Rint-clad (0.018 m) = 0.018/0.15 = 0.12
Rins-1 (0.048 m) = 0.048/0.035 = 1.371
Rmembrane (0.005 m) = 0.005/0.17 = 0.029
Rins-2 (0.2 m) = 0.2 / 0.035 = 5.714
Rwind-ins-3 (0.025) = 0.025 / 0.035 = 0.714
RTOT = 8.113 m²K/W
U = 0.123 W/m²K

Strengths and Weaknesses
Strength Weakness
01 01
02 02
03
03
Flexible plans Number of elements are needed
Opportunity of building conversion Deep floor assembling
Acoustic and fire safety issuesExposed timber elements
Only the post and shafts are load bearing
system. All the inner wall is not load
bearing, so the layout of the interior is
easy to change
Construction process: temporary
lateral bracing, number of elements
that need a crane + connections
The post-beam+ slab structure is flexible
to change to different building types. eg.
office buildings
Drop slabs and beam add complexity
to the system (HVAC, MEP, clear
height), compared to flat plate.
Acoustic and fire safety issues on the
joint of post and beam
Ability to have exposed timber elements
within residential units in a post and beam
system.
